-(-6u+x)+3(-4x-6u)=

Solution for -(-6u+x)+3(-4x-6u)= equation:

Simplifying
-1(-6u + x) + 3(-4x + -6u) = 0
(-6u * -1 + x * -1) + 3(-4x + -6u) = 0
(6u + -1x) + 3(-4x + -6u) = 0

Reorder the terms:
6u + -1x + 3(-6u + -4x) = 0
6u + -1x + (-6u * 3 + -4x * 3) = 0
6u + -1x + (-18u + -12x) = 0

Reorder the terms:
6u + -18u + -1x + -12x = 0

Combine like terms: 6u + -18u = -12u
-12u + -1x + -12x = 0

Combine like terms: -1x + -12x = -13x
-12u + -13x = 0

Solving
-12u + -13x = 0

Solving for variable 'u'.

Move all terms containing u to the left, all other terms to the right.

Add '13x' to each side of the equation.
-12u + -13x + 13x = 0 + 13x

Combine like terms: -13x + 13x = 0
-12u + 0 = 0 + 13x
-12u = 0 + 13x
Remove the zero:
-12u = 13x

Divide each side by '-12'.
u = -1.083333333x

Simplifying
u = -1.083333333x
